  • Metal Spinning: A Cost-Effective Process

    Ever notice that chandelier hanging from the ceiling or that metal bowl in your kitchen? Chances are that those items were manufactured through a process called metal spinning. The metal spinning process, also known as spin forming, is a cold metalworking process. In some ways, metal spinning is similar to other turning processes and can involve equipment similar to screw machine products, which historically have been made to manufacture fasteners, or lathes, which can be used for many purposes. These processes differ from other types of metalworking because they are...

Industry Information
View A Video on Metal Spinning - A Quick Introduction

Metal spinning, often called spin forming, is a cold metalworking process in which a flat metal disc affixed to a lathe mandrel is rotated at high speeds and formed by shaping tools. A metal spinner applies pressure to the rotating disc, which is called a blank, using several tools, which are called spoons, to shape the metal over a mandrel. This pressure can be applied by a single tool or by multiple tools. The finished product should have no wrinkling or warble, and the process is quick and cost-effective. An average metal piece will take only five to ten minutes to be formed, and very little metal waste is produced per part.

The metal spinning process can form various kinds of metals, including aluminum, titanium, stainless steel, copper and many other metals. Sheet metal spinning (service companies doing this are listed on IQS Directory) generates products used in the aerospace, food processing, healthcare, defense contracting, pharmaceutical, paper and many other industries. Engine parts, nozzles, tank heads, funnels, freezers, mixing bowls, filter housings, pressure vessels and cartridges are just a few examples of the many parts that are produced by metal spinning. Metal spinning can be done by hand, but a CNC metal spinning machine, which is short for computer numeric controlled machine, usually produces metal spun products. Flow forming is a popular alternative to spin forming; it is an advanced process that allows variation in wall thickness of the product. You can learn more about it here. Tube spinning, which produces cylinder shapes, and shear spinning, which produces cone or contoured shapes, are the two forms of flow forming. Alternative cold working processes like hydroforming are available when metal spinning and other methods are not appropriate.

Metal spinning is a cost-effective choice for forming metal, though it is usually used for smaller runs compared to other metalworking processes. When spinning cannot meet more complex design specifications, flow forming is often used. It is the main alternative to standard metal spinning and produces hollow, symmetrical shapes by using rollers to extrude a cross-sectional area of a pre-formed metal part, which is often called a blank or perform. The thickness of the part is determined by the gap that is maintained between the mandrel and the rollers. This gap may change in order to produce a product with inconsistent or uniform wall thickness. The end product parts are round in cross section but may be straight sided cones or contoured shapes. The metal that is worked into a shape is either preformed by welding or in sheet form. Heat resistant steels such as stainless steel are good materials for the flow forming process because their ductility and tensile strength are ideal for cold extrusion. Flow forming can create seamless, single pieces that have a wide range of design flexibility with increased tensile strength.

Tube forming, a flow forming method, takes tubular performs and cold works them via rollers and a mandrel to produce tubing. When shapes are made with one closed end (like a vessel), the bottom of the preform rests against the face of the mandrel while the material is moved in the same direction as the rollers. This is called forward flow forming. Reverse flow forming is a technique that produces a part with two open ends (like a tube). The force applied by rollers pushes against a serrated ring at the end of the mandrel, which compresses and extrudes the material. Shear spinning, the second method of flow forming, produces cone-shaped metal products by a flat blank that is sheared by rollers over a rotating mandrel. The diameter of the blank does not change, but the thickness decreases depending on the angle of the mandrel. No material is lost in this process. Hydroforming is an alternative to standard metal spinning and flow forming. In this process, the metal flows around a punch instead of being stretched with dyes by using a high pressure hydraulic system to create parts with very consistent thickness. There are four types of hydroforming. The most common type, tube hydroforming, is generally performed at low pressure and produces tubular parts with high integrity and structural performance. Panel hydroforming is a high pressure process that manufactures products for the automotive and aerospace industry. The third type, low pressure hydroforming, involves reshaping tubes when the cross-section definition is not strict. High pressure hydroforming, the fourth method, reshapes tubing more than the other three methods. In this type of hydroforming, the length-to-circumference ratio can change up to 50 percent.

When using metal spinning to fabricate a product, it is important to note the supplier's output capability. Some metal spinning manufacturers are not capable of short run orders and may have limitations as to the diameter and thickness of the final product desired. However, many suppliers offer sizes from a fraction of an inch to over six feet in diameter. Sometimes, a metal spinning manufacturer will only have the capacity to spin a certain type of metal, such as stainless steel or aluminum. Though not all manufacturers can offer every type of spinning service, metal spinning can mean lower tooling costs because spinner dies are simpler and cheaper. Spinning tooling can also be made in-house by many spinning shops, meaning shorter lead times. The spinning process often work-hardens the metal product as it is being shaped, providing a stronger end product. The metal spinning business continues to grow as the process becomes better through technological advances.

Types of Metal Spinning

  • Aluminum spinning produces round, axially symmetrical aluminum parts by rotating aluminum sheet metal on a spinning lathe and forming it with tools.
  • CNC metal spinning (computer numerical controlled spinning) and related technology are most often used during the metal spinning process. Today’s modern CNC technology has made it possible to produce high volume, close tolerance, concentric metal parts quickly and economically. CNC machine spinners are also used for the fabrication of other sheet metal parts.
  • Copper spinning produces round, axially symmetrical copper parts by rotating copper sheet metal on a spinning lathe and forming it with tools.
  • Custom metal spinners are what the majority of metal spinning shops use. Because of flexible rapid tooling and the short set up times associated with the technique, the costs of metal spinning can be much lower than other metal fabrication techniques.
  • Flow forming is an advanced form of spin forming that allows for variable wall thickness in the metal products it creates.
  • Hand metal spinners are still used by some manufacturers but are increasingly rare. The spinning of the metal is machine controlled but the application of pressure is done by hand, making for a very hard and cumbersome process; the results sometimes lack uniformity from piece to piece.
  • Hydroforming is a tool and die process that uses hydraulic fluid to make components, often for the automotive industry.
  • Metal spinners produce round, axially symmetrical metal parts by rotating sheet metal on a spinning lathe and forming it with tools.
  • Shear spinning is a metalworking process that produces conic or contoured, hollow metal products that have a uniform or purposely varied wall thickness.
  • Sheet metal spinning produces round, axially symmetrical parts, usually for prototyping purposes, by rotating sheet metal on a spinning lathe and forming it with tools.
  • Spin forming is a metalworking process that produces round, axially symmetrical parts by rotating sheet metal on a spinning lathe and forming it with tools.
  • Stainless steel spinning is the most prominent type done by metal spinning shops. Most, however, are capable of spinning a wide range of common to exotic metals, including aluminum, brass, copper, hastelloy and titanium.
  • Tank heads are circular, pressed ends to cylindrical tanks.
  • Titanium spinning is a way to create light yet strong spun products that are resistant to corrosion and offer a lustrous appearance.
